EPROM Boot Select. When EBOOT is high, the ADSP-2106x
is configured for booting from an 8-bit EPROM. When
EBOOT is low, the LBOOT and

configuration selection which should be hardwired.
Link Boot – Host Boot Select. When LBOOT is high, the
ADSP-2106x is configured for link port booting. When
LBOOT is low, the ADSP-2106x is configured for host
processor booting or no booting. See table below. This
